text: Spin mixtures of degenerate fermions are a cornerstone of quantum many-body
physics, enabling superfluidity, polarons, and rich spin dynamics through s-wave
scattering resonances. Combining them with strong, long-range dipolar interactions
provides highly flexible control schemes promising even more exotic quantum phases.
Recently, microwave shielding gave access to spin-polarized degenerate samples
of dipolar fermionic molecules, where tunable p-wave interactions were enabled
by field-linked resonances available only by compromising the shielding (due to
experimental limitations). Here, we study the scattering properties of a fermionic
dipolar spin mixture and show that a universal s-wave resonance is readily accessible
without compromising the shielding. We develop a universal description of the
tunable s-wave interaction and weakly bound tetratomic states based on the microwave-field
parameters. The s-wave resonance paves the way to stable, controllable and strongly-interacting
dipolar spin mixtures of deeply degenerate fermions and supports favorable conditions
to reach this regime via evaporative cooling.

text: We present a general theoretical framework for helical dichroism (HD), establishing
an explicit link between chiral resolution and orbital angular momentum (OAM)
exchange in light–matter interaction. Tracing microscopic mechanisms of the OAM
transfer, we derive rotational selection rules, which establish that HD emerges
only from the spin–orbit coupling of light, even for beams without the far-field
OAM. Our findings refine the conditions for observing HD, provide a tool to re-examine
the outcome of prior experiments, and guide future designs for chiral sensing
with structured light.

text: In this paper we examine how porosity fluctuations affect the hydrodynamic
permeability of a porous matrix or membrane. We introduce a fluctuating Darcy
model, which couples the Navier-Stokes equation to the space- and time-dependent
porosity fluctuations via a Darcy friction term. Using a perturbative approach,
a Dyson equation for hydrodynamic fluctuations is derived and solved to express
the permeability in terms of the matrix fluctuation spectrum. Surprisingly, the
model reveals strong modifications of the fluid permeability in fluctuating matrices
compared to static ones. Applications to various matrix excitation models, the
breathing matrix, phonons, and active forcing, highlight the significant influence
of matrix fluctuations on fluid transport, offering insights for optimizing membrane
design for separation applications.

text: Cold atom experiments show that a mobile impurity particle immersed in a weakly
interacting Bose-Einstein condensate forms a well-defined quasiparticle (Bose
polaron) for weak to moderate impurity-boson interaction strengths, whereas a
significant line broadening is consistently observed for strong interactions.
Motivated by this, we introduce a phenomenological theory based on the assumption
that the most relevant states are characterized by the impurity correlated with
at most one boson, since they have the largest overlap with the uncorrelated states
to which the most common experimental probes couple. These experimentally relevant
states can, however, decay to lower energy states characterized by correlations
involving multiple bosons, and we model this using a minimal variational wave
function combined with a complex impurity-boson interaction strength. We first
motivate this approach by comparing to a more elaborate theory that includes correlations
with up to two bosons. Our phenomenological model is shown to recover the main
results of two recent experiments probing both the spectral and the nonequilibrium
properties of the Bose polaron. Our work offers an intuitive framework for analyzing
experimental data and highlights the importance of understanding the complicated
problem of the Bose polaron decay in a many-body setting.

text: Despite its pivotal role in optical manipulation, high capacity communications,
and quantum information, a general measure of orbital angular momentum (OAM) in
structured light remains elusive. In optical fields, where multiple vortices coexist,
the local nature of vortex OAM and the absence of a common rotation axis make
the total OAM of the field difficult to quantify. Here, we introduce the R index—a
metric that captures the intrinsic OAM content of any structured optical field,
from pure Laguerre–Gaussian modes to arbitrary multi vortex superpositions. Not
only does this metric quantify the total OAM, it also assesses field purity, providing
insight into the fidelity and robustness of the OAM generation. By unifying OAM
characterization into a single figure of merit, the R index enables direct comparison
across diverse beam profiles and facilitates the identification of optimal configurations

text: Kapitza-Dirac scattering, the diffraction of matter waves from a standing
light field, is widely utilized in ultracold gases, but its behavior in the strongly
interacting regime is an open question. Here, we develop a numerically exact two-body
description of Kapitza-Dirac scattering for two contact-interacting atoms in a
one-dimensional harmonic trap subjected to a pulsed optical lattice, enabling
us to obtain the numerically exact dynamics. We map how interaction strength,
lattice depth, lattice wave number, and pulse duration reshape the diffraction
pattern, leading to an interaction-dependent population redistribution in real
and momentum space. By comparing the exact dynamics to an impulsive sudden-approximation
description, we delineate the parameter regimes where it remains accurate and
those, notably at strong attraction and small lattice wave number, where it fails.
Our results provide a controlled few-body benchmark for interacting Kapitza-Dirac
scattering and quantitative guidance for Kapitza-Dirac-based probes of ultracold
atomic systems.

text: The transport properties of nanofluidic channels are usually studied under
constant (DC) voltage or pressure driving. However, the frequency response under
sinusoidal (AC) drivings offers rich insights into the time-dependent transport
mechanisms. Inspired by recent electrochemical approaches, we investigate the
couplings between ionic and electronic transport under AC driving. We show that
conduction electrons of the channel walls participate in ionic current via capacitive
electrochemical coupling, defining a critical frequency and length scale where
electron-dominated conductivity emerges. We further analyze how electron–ion coupling
modifies electro-osmotic flows and demonstrate that fluctuation-induced momentum
transfer between the electrolyte and wall electrons produces distinct AC transport
signatures, depending on the charge carrier polarity. Altogether, we establish
a frequency-dependent transport matrix that couples ionic, electronic, and hydrodynamic
flows. These findings establish AC nanofluidic transport as a powerful probe of
interfacial phenomena under confinement and suggest new directions for engineering
nanofluidic functionalities through electron–electrolyte coupling.

text: An in-operando electro-intercalation method for the on-chip synthesis of alkali-metal-intercalated
materials and their Raman spectroscopic and transport characterization in ultrahigh
vacuum (UHV) is developed. We apply this method to synthesize fulleride superconductors
via Rb+ intercalation into a C60 film. During the intercalation, we monitor the
stoichiometry via UHV-Raman spectroscopy and probe superconductivity via transport
measurements. An increase of the superconducting transition temperature from 7.0
K to 14.5 K is observed when the stoichiometry is tuned from Rb2.7C60 to Rb3C60.
In our experiment, an ionic Rb+ flux into the host material is induced by an applied
electronic current via a Butler–Volmer-type mechanism. Electro-intercalation captivates
through improved stoichiometric precision, the ability to smoothly vary stoichiometry
via duration of current application, and the absence of a lower limit of the volume
of the host material. It represents a powerful concept for the on-chip synthesis
of intercalated materials, battery research, and beyond.

text: We derive an analog of the Lellouch-Lüscher (LL) relation for few-body bosonic
systems, linking few-body scattering loss rates to the energies and widths of
the corresponding harmonically trapped few-body states. Three-body numerical simulations
show that the LL relation applies across a broad range of interaction strengths

partial wave. Our Letter establishes a robust theoretical framework for understanding
the role of the finite-volume effect in few-body observables in optical lattice
and tweezer experiments, enabling precise determination of multibody scattering

text: We demonstrate that periodically driven quantum rotors provide a promising
and broadly applicable platform to implement multigap topological phases, where
groups of bands can acquire topological invariants due to non-Abelian braiding
of band degeneracies. By adiabatically varying the periodic kicks to the rotor
we find nodal-line braiding, which causes sign flips of topological charges of
band nodes and can prevent them from annihilating, indicated by nonzero values
of the patch Euler class. In particular, we report on the emergence of an anomalous
Dirac string phase arising in the strongly driven regime, a truly out-of-equilibrium
phase of the quantum rotor. This phase emanates from braiding processes involving
all (quasienergy) gaps and manifests itself with edge states at zero angular momentum.
Our results reveal direct applications in state-of-the-art experiments of quantum
rotors, such as linear molecules driven by periodic far-off-resonant laser pulses
or artificial quantum rotors in optical lattices, whose extensive versatility
offers precise modification and observation of novel non-Abelian topological properties.

text: 'A phase plate has long been sought in transmission electron microscopy (TEM)
to maximize the image contrast of weakly-scattering objects like biomolecules.
The laser phase plate (LPP) has recently demonstrated that an amplified, focused
laser standing wave reliably phase shifts the electron beam, achieving phase-contrast
TEM. Building on the single-beam LPP, here we introduce the crossed laser phase
plate (XLPP): two laser standing waves which intersect in the diffraction plane.
We present a theoretical model for the XLPP inside the microscope and show that,
relative to the original LPP, it increases information transfer at low spatial
frequencies while suppressing ghost images formed by Kapitza-Dirac diffraction.
We also present a simple acquisition scheme, enabled by the XLPP, which further
suppresses ghosts. Finally, we discuss practical considerations of XLPP design
and show experimental results from a prototype. The results of this study chart
the course for future developments of LPP hardware.'

text: Phase plates can, in principle, overcome the poor image contrast in cryo–electron
microscopy (cryo-EM) and the resulting limits on the structural reconstruction
of small proteins. However, previous designs have been unstable and compromised
the high-resolution signal and have thus been unable to surpass results achieved
by standard cryo-EM. Here, we show that the laser phase plate (LPP), installed
in a modern, custom Titan Krios microscope, enhances the resolution in single-particle
reconstruction of small proteins by improving specimen-motion correction and recovery
of information from the early frames, as well as particle visualization, three-dimensional
classification, and alignment. These advances use standard defocus ranges and
reconstruction procedures but open the door to LPP-tailored protocols, offering
further improvements by leveraging the LPP demonstrated here.

text: Mechanosensitive ion transport plays a central role in enabling living systems
to perceive and adapt to their environment through the deformation of soft, embedded
ion channels. In this work, we demonstrate that ion transport within a two-dimensional
graphite nanoslit can be rationally engineered to achieve a bipolar, pressure-sensitive
response without any structural deformation. The mechanosensitivity arises from
the selective charging of one channel inlet, which acts as a reversible source
of mobile charge carriers. These excess ions can then be advected in or out of
the channel by the pressure-driven water flow, thereby modulating the ionic conductance.
This mechanism is captured through a comprehensive electrohydrodynamic model that
analytically accounts for coupled diffusion, convection, surface transport, diffusio-osmosis,
and interfacial slippage, both inside and outside the nanoslit. The theoretical
framework quantitatively reproduces the experimental data, showing that a simple
surface charge pattern can give rise to complex, pressure-dependent conductance.
These findings reveal how rich nonlinear couplings at the nanoscale can be harnessed
to design adaptive, bioinspired nanofluidic systems, exemplified here by ionic
pressure sensors.

text: The influence of chiral molecular potentials on phase-coherent transport
in superconducting Josephson junctions is investigated. Within a Bogoliubov–de
Gennes tight-binding framework, a superconducting-normal-superconducting (SNS)
junction functionalized by adsorbed chiral molecules is modeled, where electrostatic
gradients generated by the molecules induce spin-orbit coupling in the normal
region. The equilibrium charge current-phase relation is found to remain largely
insensitive to molecular chirality in symmetric, zero-field configurations. In
contrast, the spin-polarized equilibrium current exhibits a pronounced chirality-dependent
response, with opposite enantiomers producing distinct and anisotropic spin-polarized
Josephson currents. The resulting handedness contrast can be enhanced through
control parameters such as molecular orientation and the strength of the induced
spin-orbit coupling. The temperature dependence of these currents further shows
that the chirality-dependent signatures persist across a range of temperatures
well below the superconducting critical temperature. These results identify Josephson
interferometry as a phase-sensitive setting for probing chirality-dependent spin
structure and highlight spin-polarized superconducting transport as a controlled
route toward integrating chiral molecular functionality into superconducting spintronic
devices.

text: We investigate the nonequilibrium dynamics of core-hole excitations in a one-dimensional
fermionic few-body system consisting of a spin-polarized Fermi bath coupled to
a single heavy mobile impurity. The bath is initially prepared in a particle-hole
configuration by emptying a selected bath single-particle orbital, while the impurity
is displaced with respect to the center of the bath confinement potential. The
quench dynamics are initialized by suddenly switching on the impurity-bath interaction.
To resolve the resulting dynamics, we combine two complementary ab initio approaches,
namely, the MultiLayer MultiConfiguration Time-Dependent Hartree method for mixtures
and a multichannel Born-Oppenheimer framework. We show that the postquench response
is governed by the interaction strength, impurity confinement, mass imbalance,
and the location of the initially prepared hole within the Fermi sea. The density
evolution and impurity center-of-mass motion reveal a competition between mixing
and demixing of impurity and bath, while the von Neumann entropy demonstrates
the buildup of pronounced many-body correlations. Most importantly, the occupation
dynamics of the initially emptied orbital identifies deep core holes as substantially
more robust against refilling than bulk or edge vacancies. Our results establish
core-hole excitations as robust dynamical many-body features in trapped ultracold
fermions and provide a controlled route toward probing orthogonality response,
correlation buildup, and hole refilling in real time.

text: 'Even though the one-dimensional contact interaction requires no regularization,
renormalization methods have been shown to improve the convergence of numerical
calculations considerably. In this work, we compare and contrast these methods:
“the running coupling constant” where the two-body ground-state energy is used
as a renormalization condition, and two effective interaction approaches that
include information about the ground as well as excited states. In particular,
we calculate the energies and densities of few-fermion systems in a harmonic oscillator
with the configuration-interaction method and compare the results based upon renormalized
and bare interactions. We find that the use of the running coupling constant instead
of the bare interaction improves convergence significantly. A comparison with
an effective interaction, which is designed to reproduce the relative part of
the energy spectrum of two particles, showed a similar improvement. The effective
interaction provides an additional improvement if the center-of-mass excitations
are included in the construction. Finally, we discuss the transformation of observables
alongside the renormalization of the potential, and demonstrate that this might
be an essential ingredient for accurate numerical calculations.'

text: Impurity motion in a many-body environment has been a central issue in the
field of low-temperature physics for decades. In bosonic quantum fluids, the onset
of a drag force experienced by point-like objects is due to collective environment
excitations, driven by the exchange of linear momentum between the impurity and
the many-body bath. In this work we consider a rotating impurity, with the aim
of exploring how angular momentum is exchanged with the surrounding bosonic environment.
In order to elucidate these issues, we employ a quasiparticle approach based on
the angulon theory, which allows us to effectively deal with the non-trivial algebra
of quantized angular momentum in the presence of a many-body environment. We uncover
how impurity dressing by environmental excitations can establish an exchange channel,
whose effectiveness crucially depends on the initial state of the impurity. Remarkably,
we find that there is a critical value of initial angular momentum, above which
this channel effectively freezes.

text: We investigate a molecular quantum rotor in a two-dimensional Bose-Einstein
condensate. The focus is on studying the angulon quasiparticle concept in the
crossover from few- to many-body physics. To this end, we formulate the problem
in real space and solve it with a mean-field approach in the frame co-rotating
with the impurity. We show that the system starts to feature angulon characteristics
when the size of the bosonic cloud is large enough to screen the rotor. More importantly,
we demonstrate the departure from the angulon picture for large system sizes or
large angular momenta where the properties of the system are determined by collective
excitations of the Bose gas.
